Abstract
In response to the British Columbia forestry industry’s need for an alternate market for its MPB logs, we conducted a study to determine if allocating this type of wood to the activated charcoal industry is a feasible solution. The study was done via a literature review, telephone calls, and interviews. Our economic analysis showed that local producers can profit from making activated charcoal from MPB wood as long as their costs are no more than three times those of their overseas counterparts. The present charcoal industry allocates a specific input material to make a charcoal product. Wood-based charcoal cannot produce a hardness number and has fewer micropores than competing materials, which are required for the lucrative bottled water market. Hence, wood is usually restricted to making products that decolorize or apply preliminary effluent treatment. North American and Asian companies employed similar input material/final product combinations. We did not find a North Amercian-based company that made wood-based activated charcoal. Lower overseas salaries and other expenses were the most obvious reasons for this observation. Recent overseas cellulose-based activated charcoal research has focussed on minimizing environmental impact and maximizing the quantities of useful by-products that are yielded from the synthesis process.

Abstract
Powder and liquid phenol-formaldehyde (PF) combination binder system has been commonly used in North America for oriented strand board (OSB) manufacturing. This binder system has shown its suitability for improving resin efficiency and bond quality as compared with either powder PF (PPF) or liquid PF (LPF) resin. This study was conducted to investigate the effect of resin application sequence (LPF-PPF-LPF, LPF-PPF, PPF-LPF), resin content (3.0%, 5.5%, 8.0%), and PPF/LPF combination ratio (50:50, 65:35, 80:20) on strand board performance. Board properties evaluated include internal bond (IB), thickness swelling (TS), water absorption (WA), dry and wet modulus of rupture (MOR), dry modulus of elasticity (MOE), edgewise shear, and compression shear strength. In addition, a non-destructive test method (TROBEND) developed at Forintek was also used to measure the modulus of elasticity (MOE) and shear modulus of elasticity (G). Response Surface Methodology (RSM) was used in the experiment design. Significant response surface models were established for individual panel properties, including the linear model for IB, dry MOR, dry MOE, and compression shear, as well as the quadric model for TS, WA, and wet MOR, and 2FI (two factor interaction) for edgewise shear. ANOVA for response surface model indicated that the resin content was a significant model term for IB, TS, dry MOR and MOE, wet MOR, and compression shear properties. An increase in resin content improved these board properties. Powder/liquid ratio was a significant model term for TS, WA, and wet MOR. Resin application sequence was not a significant model term for any panel property, but its interaction with resin content was a significant model term for edgewise shear property. In most cases, the interactions between experimental variables were not significant model terms for predicting panel properties, but they still revealed some trends. Regarding Sequence 3 (PPF-LPF), 50:50 PPF/LPF ratio (lower level) resulted in higher IB, dry MOR, and compression shear, while 80:20 PPF/LPF (higher level) yielded lower WA and higher dry MOE. For Sequence 2 (LPF-PPF), 65:35 PPF/LPF ratio (middle level) favoured TS, while 50:50 PPF/LPF ratio (lower level) favoured wet MOR. Sequence 1 (LPF-PPF-LPF) combined with 50:50 PPF/LPF ratio (lower level) also gave lower WA values. In general, an increase in resin content improved the board properties with the above combinations. In addition, Sequence 3 (PPF-LPF), with 3.0% resin (lower level), yielded higher edgewise shear strength regardless of resin application sequence. An attempt was made to correlate the panel mechanical properties measured using both destructive and non-destructive test methods. The strongest correlation was observed between IB and compression shear (R2=0.70), followed by TORBEND G with modulus of elasticity (TORBEND MOE) (R2=0.40), and TORBEND G with compression shear (R2=0.28) and with IB (R2=0.26). However, no correlation seemed to exist between MOE (static bending) and TROBEND MOE. An image analysis indicated that an increase in resin content significantly increased resin coverage on strand surface. At each resin content (3.0%, 5.5%, and 8.0%), a decrease in PPF/LPF ratio in Sequence 1 (LPF-PPF-LPF) or an increase PPF/LPF ratio in sequence 3 (PPF-LPF) seemed to result in higher resin coverage. Resin coverage seemed to correlate to TS (R2=0.45), IB (R2=0.42), compression shear (R2=0.39), TORBEND G (R2=0.39), dry MOR (R2=0.25), wet MOR (R2=0.25), and dry MOE (R2=0.18). However, resin coverage did not seem to correlate to WA, TORBEND MOE, or edgewise shear properties.

Abstract
Le défilement des arbres est une caractéristique reconnue pour affecter considérablement le rendement en sciages lors du débitage des billes. Il est admis que la croissance plus rapide des arbres, notamment suite à des traitements d’éclaircie du peuplement, produit des tiges à défilement plus élevé lors de la récolte. Le défilement des billes a toujours représenté un défi au sciage et il y a eu bien des débats sur la façon de débiter les billes en minimisant l’impact du défilement sur le rendement en sciages. L’avènement des tables de positionnement optimisé a rendu ces débats beaucoup moins pertinents puisque ces équipements permettent l’optimisation du positionnement de chaque plateau avant le débitage. L’optimisation du positionnement est toutefois limitée lorsque les équipements utilisés au second débitage sont composés d’une équarrisseuse suivie d’une débiteuse à scies multiples. En effet, les restrictions sur le décentrage des plateaux et sur l’ouverture des têtes de l’équarrisseuse désavantagent plus les billes de fort défilement puisque la quantité de fibre contenue dans le défilement va directement en copeaux. Une méthode dite « sciage en bouteille » a été proposée et employée par certains industriels. La méthode préconisée dans la présente étude est une variante nommée « débitage en demi-bouteille ». Cette variante permet de maximiser la récupération dans le défilement en le plaçant d’un seul côté. Une des têtes de l’équarrisseuse reste d’un côté toujours à la même position durant le débitage, tandis que la seconde tête s’ouvre davantage vers le tiers de la bille, d’une dimension correspondant à l’épaisseur nominale d’une pièce de 1 ou de 2 pouces. Le simulateur de débitage Optitek a été utilisé pour vérifier si cette méthode présente des gains par rapport aux méthodes présentement employées dans les scieries. Des lots de billes ont été constitués selon deux catégories de longueur, 16 et 12 pieds, et chaque ensemble de billes a ensuite été séparé en trois classes de défilement (faible, moyen et fort défilement). Les résultats montrent que la méthode de débitage en demi-bouteille est avantageuse pour les scieries transformant des billes de 12 pieds et plus sur des lignes utilisant des tables de positionnement des plateaux devant l’équarrisseuse, et ce pour toutes les classes de défilement. La méthode « en demi-bouteille » permet de récupérer davantage de pièces de sciage dans le défilement de la bille, en permettant l’ouverture d’une des têtes équarrisseuses lorsque la bille est suffisamment maintenue dans le système de débitage. Des gains monétaires variant de 6,5 % à 8,9 % ont été observés pour les billes de 16 pieds de longueur et de 4,0 % à 5,1 % pour les billes de 12 pieds de longueur lorsque la méthode de débitage en demi-bouteille est utilisée au lieu de la méthode de l’équarrisseuse optimisée. On constate que les gains sont supérieurs lorsque les billes sont plus longues. Par contre, l’augmentation du défilement n’engendre pas d’augmentation des gains. Le débitage en demi-bouteille s’avère donc une alternative intéressante au débitage avec table de positionnement devant une équarrisseuse. Toutefois, le meilleur système de débitage en ce qui concerne les rendements demeure la débiteuse à scies multiples, précédée d’une table d’optimisation, car il présente beaucoup moins de contraintes de positionnement.

Abstract
The merchantable tree-length size and quality has decreased over the past four (4) years. The average volume per merchantable tree-length was 0.876 cubic meters in 1985 versus only 0.705 cubic meters in 1989. This situation has forced Commonwealth Plywood to merchandize the company veneer grade of Deroulable in order to support its veneer plant. The resource merchandizing study identified a 3.5% veneer and 20.7% Deroulable recovery compared to a 40.4% veneer volume in 1985. By accepting a lower grade of veneer, the company is also manufacturing lower quality sawlogs. For tree-lengths containing butt rot or other veneer limiting defects such as: shake and seams, short F-1 or F-2 sawlogs were bucked to produce a veneer log once defects were removed. From tree-lengths containing little or no rot, lower quality sawlogs were merchandized further up the tree stem as a result of taking Deroulable veneer from the butt section. The general quality of the 1989 study sawlogs was better than the 1985 SIP sawlogs at the expense of recovering a lower volume and grade of veneer. The impact of this improved sawlog quality has benefited the conversion efficiency at the sawmill as opposed to the veneer mill. The lumber volume recovery dropped from 195bf per m3 in 1985 to 177 bf per m3 in 1989. On the other hand, lumber grade recovery was better for the 1989 study compared to the 1985 SIP as shown by the No.1 Common and Better recoveries of 35.7 versus 18.0%, respectively. The net effect of a higher grade recovery more than offset th lower volume recovery as summarized by the sawmill profitability analysis. The gross profits (before taxes) were -$6.54, +$8.42 and -$38.43 per Mbf lumber tally for the 1985 SIP study, the 1989 study and the 1989 long-term company average, respectively. The gross profit for the 1989 study sawlogs was significantly higher than for the present long-term results due to a better combination of lumber volume and grade recovery. The sawmill profitability analysis for the 1989 study logs differs greatly compared to the company's long-term average raising a question concerning the selection of a representative sawlog sample. Sawlog quality is a direct reflection of the resource quality. Furthermore, sawmill profits will vary considerably with sawlog quality. With a declining resource quality and a compay policy of maximizing veneer volume, there is increasing pressure on the veneer mill and sawmill to improve profitability as profit centres. Since Commonwealth Plywood is an integrated veneer/sawmill company, poor resource allocation will generally impact each profit centre in an offsetting manner. However, a serious decline in resource quality and improper resource merchandizing will adversely affect both the veneer and sawmill significantly. This study observed certain log making procedures that will improve the overall operating efficiency of both the veneer plant and sawmill. Recommendations are provided to address problems of tree-length merchandizing and sawlog scaling impacting on company profitability.
